PennDOT District 12 is responsible for the design, construction and maintenance of I-70 from the West Virginia state line east to New Stanton, PA (Exit 57). Much of the corridor was originally designed and built more than 55 years ago; therefore, many improvements are underway and/or planned to meet modern traffic needs. To date, 7 improvement projects have been completed, 7 are being constructed, 4 are in the design phase, and 2 are planned for the future. PennDOT District 12 will invest nearly $500 million to deliver the improvement projects which will include interchange improvements, bridge replacements or reconstructions, and miles of improved roadway and upgrades to the interstates intelligent transportation systems. More details are provided below. The goal of this website is to provide users with a single resource to gauge the status of all of these improvement projects.
